Below you see a site I am currently working on in Fc. I have searched the forums high and low for the answer on how to create a lightbox-style gallery without using data lists (unless a DL is preferred on this).

What I want to do: Upon clicking on the individual images, the thumb is enlarged to a higher res while the background is greyed/darkened.

I dont want a scrolling list, I just have no idea where to begin and every place I look recommends a scrolling data list.
